“WHY DO SOME GENETIC MUTATIONS LEAD TO CANCER WHILE OTHERS DON’T? Scientists used to think that genetic mutations – changes to the letter sequence of your DNA – were the foundation of all cancers. They were only partly right. “Mutations are very important – but they’re not the entire explanation for a tumour,” said Douglas Hanahan, a distinguished scholar at the Ludwig Institute for Cancer Research in Lausanne, Switzerland. Some mutations remain dormant our whole lives, never leading to cancer. It’s now clear that, separate from DNA mutations, there are other factors that alter how genes are expressed. These are called epigenetic changes, and scientists have discovered that they play a huge role in driving cancer.” https://cnalifestyle.channelnewsasia.com/wellness/cancer-causes-risk-factors-treatment-459306#:~:text=WHY%20DO%20SOME,in%20driving%20cancer.
